Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Beyond the annotations (readOnlyHint=false, idempotentHint=true, destructiveHint=false), it discloses the auth requirement ('Requires the organization API key'), the scheduled-block cadence, and the no-op behavior on empty queues. It does not say what a successful seal returns or costs, but the idempotent hint already signals repeat-call safety.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Three short sentences, front-loaded with the action and its timing benefit, followed by the no-op condition and the auth prerequisite. No redundant restatement of the title and nothing extraneous.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a zero-argument, non-destructive trigger with no output schema, the description covers action, timing, empty-queue behavior, and auth needs. Only the success-side outcome (what the caller learns after sealing) is left implicit, which keeps it just short of complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The tool takes zero parameters, so there is nothing for the description to disambiguate; baseline for a no-param tool applies. The description correctly avoids inventing inputs and instead explains the implicit org-key auth context.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource ('Seal your newest entries into a quantum block') plus the timing effect ('now instead of waiting for the next scheduled block'). It does not name or contrast with the nearby siblings (qledger_block, qledger_status, qledger_verify_chain), so the agent must infer which one reads versus seals.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

Gives a clear trigger condition ('instead of waiting for the next scheduled block') and an explicit no-op case ('Does nothing if no entries are waiting'), which tells the agent when not to expect an effect. It stops short of naming an alternative tool to call when waiting is preferable.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
